SHINGLE STRIP. l y

Application led October 2,1924. Serial No. 741,118.

v This invention relates to improvements in shingle strips, andspecifically contemplates so severing and slitting a continuous sheet ofpreviously prepared roofing material as to produce individual shinglestrips, which when laid on a roof, present correspondinghexa onal areasof light, dark and shadow. lThe lnvention is characterized by the factthat the strips can be produced with-out any waste in cutting and areself-spacing relative each other, when placed on a roof;

Briey, the Sheet of previously prepared roofing material may becompletely severed centrally of its length and adjacent this centralline of severance at right angles thereto is also completely severed atprededetermined intervals corresponding to the width desired.Communicating with each of the latter vertical lines of severance, is aright angled cut, parallel to the central line of severance. From thelatter line of severance are communicating diagonal lines of severance,the outer set of diagonal lines connecting With a relatively short lineof severance, again parallel to the central severing line. Thisrelatively short` line of severance communicates with right angled linesof severance, terminating at the edges 'of the roofing sheet. Further,'a set of op posed half hexagonal incisions are produced intermediateeach complete line of severf' ance. The individual strip thus producedhas u per and lower straight edges while the si es are staggeredrelative to the upper and lower edges, but parallel to eachother,

' having semihexagonal incisions in 'the body thereof."` The lowerportion is then folded along theunbroken connecting lines'upon the upperbody portion, resulting in the' formation of a stri exhibiting perfecthexagonals, which 'w en laid on a roof,

resents a series of staggered or parallel liexagonals of alternatelycontrasting light and dark colors.`

Many wdvanta es will be apparent to those skilled in e art, among whichmay be mentioned the economy. of construction, the self-spacing whenlaid ona roof, the reinforcing structural characteristics produced, andthe attractive hexagonal areas of contrastin .color presented to `theeye.

In the rawings;

Fig. 1'is a plan view of a continuous roofing sheet severed and. incisedto l produce my improved shingle strip. f

171g. 2 is va plan view of the individual strip wlth the lower portion'folded over the upper portion.

Fig. 3 is an edge view of the construction .shown 1n Fig'. 2.

Fig. 4 is a plan view of the strips aslsembled in place on a roof,illustrating one form of arrangement. Referring in detail to thedrawings, l designates as a whole a continuous sheet of felt previouslysaturated with a ,Waterproof-v ing composition, and one or both surfacesof which may have imposed thereon a granular surfacing of apredeterminedv color, althoughA in the preferred form of invention, onesurface only may be coated with the granularmaterial, the oppositesurface presenting a plain appearance, for instance, black, whereasphalt is used as the saturant. The granular material may be any colorsuch asred, green, gray, slate, etc.

AS this sheet is fed forward, it is longitudinally severed centrally ofits width along the line 2, and also vertically severed along the line 3bisecting the line 2. The

lines 3 terminate in right angle severing lines 4, from Whichextenddiagonals 5 .and 6. The diagonal 5 terminates within lthe body of thematerial, while the diagonal lin(` 6 has a short angular extension 7parallel to the central line of severancel 2. The latter extension 7terminates in a right angled severing line 8, which terminates adjacentthe edges of the sheet to produce complete severance. Intermediate theedges of each shingle strip are produced semi-hex-l agonal incisions 9for a purpose hereinafter explained.

The individual shingle strip produced by severing a sheet of roofingmaterial as de scribed heretofore, has u per and lower straight(parallel edges While the sides 'are staggere -relative to the upper andlower edges, but the staggered lines per se are parallel to each other.Thebottom portionof the individual shingle strip along the unseveredlines between the 'extremities ofv the semi-hexagonal lines ofseverance, and the sides being staggered relative to the upper and loweredges, a novel and attractive appearanee is the result. The extremitiesof uns the incisions 9 within the body of the sheet preferably terminateata point beyond the longitudinal central cross section, yin order thatthe upper edge of the'portion which is folded over may project beyondthe upper edge of the portron which has not been folded. In this Way,there is formed parallel or staggered hexagonalv4 areas when the stripis laid on aroof in combination with other strips, While at the sametime utilizing the particular construction of the strips to accomplishtheir own vself-spacing.

One surface only may have granular material applied thereto of apredetermined color, While the other surface-may be devoid of granularmaterial and present the color of the waterproofing material, forinstance, black, where asphalt is the waterproof material used. Thus,the assembled shingles on a roof present contrasting hexagonal fields ofdark, light and shadow, as shown.' Or, both surfaces may have granularmaterial imposed thereon, of different colors, for in-` stance, red andgreen, slate and red, etc'.

Further, the shingles may be so laid as to present parallel areas oflight and dark,` or they may be staggered relative to each other.

The strips may beheld in place by any suitable means, such a's hollownails, etc., driven into the bod portion and concealed from view by thefolded portion. The entire construction is extremely sturdy, and thereinforcing qualities of the doubled ply will be instantly appreciated.Furthermore, the finished roof gives the impression of solidity `andstrength, combined with beauty and attractiveness.

It is understood of course, that shingle strips can be produced froml asheet half aS Wide as that described, thus eliminating the line 2.

I claim as my invention:

1. A shingle strip vof greater Width than length, having two parallelstraight sides and two sides staggered relative the stra-ight sides butparallel with each other, having a semi-hexagonal incision in the bodyof the strip, and folded along the lines of the. semihexagonal incisionto produce hexagonal areas.

12. A shingle strip of greater width than length having on one surfacegranular material of a predetermined color and the opposite surfacepresenting a contrasting color, having two parallel straight' sides andtwo sidesl staggered relative =thejstraight sides but parallel With eachother, having semihexavonal incisions in the body of the strip, andfolded along the lines of the semi-hex vv'agonal incisions to producehexagonal areas grally connected overlying portion folded.

upon the body portion, sald overlying portion being of substantiallythesalne configuration as'the body portion.

4a.. As a new article of manufacture, a

flexible roofing kstrip originally having onl one' surface granularmaterial ofa predeter mined color and originally on the opposite surfacea contrasting color, comprising a strip having parallel' longitudinaledges, sides disposed partially at right angles and partially staggeredvrelativev said longitudinal edges but parallel with each other` the baseof said strip exhibiting alternate cntout portions and interposedtabsbetween the cut-outs, both being substantially semi-hexagonal in shapeand an integrally connected overlying portion folded upon thebodyportion to produce' hexagonal. areas, the latter bein of substantiallythe same configuration as the body portion, but of a 'contrasting color.

5. As anew article of manufacture, a flexible rooting strip comprising abody portion having granular material of a. redetermined color imposedthereon, and an integrally connected overlyin portion of the samecontiguration as the body portion, Ahaving a surface of contrastingcolor and disposed in a plane offset from the plane of the body portion.
